On Saturday, Ronaldo became the first player to reach 400 goals in Europe's top five leagues as he got the opener in Juve's 1-1 draw at home to Genoa.
Since moving to Turin, Ronaldo has been sued over an alleged rape in Las Vegas in 2009. He has denied the allegations and says he has a "clear conscience."
Ronaldo left the field with tears in his eyes after being sent off during his Champions League debut for Juventus in Valencia. The Portugal star feared he would miss his return to former club Manchester United, but was given just a one-match ban.
Cristiano Ronaldo made his Serie A debut for Juventus on August 18 in a thrilling 3-2 win at Chievo.
His move to Juventus from Real Madrid after the World Cup was arguably the most surprising transfer of the 2018 summer window given he had been at the Spanish club for nine years.
During his nine years with Real, Ronaldo won six trophies and scored 451 goals.
Ronaldo joined Juve for a reported $117 million transfer fee. Last season, the Portuguese star scored a stunning bicycle kick against Juve in Turin, which was widely viewed as one of world's greatest ever Champions League goals.
Juve has dominated Italian football in recent years, but the Italian club last won the Champions League in 1996. The expectation is that Ronaldo, who is a five-time Ballon d'Or winner and helped Real Madrid win Europe's most prestige competition four times, will redress that balance.
